Glancing around, everything in front of him made Ling Feng gasp, this is a big underground hole, it is really far bigger than he imagined, from the ground to the top, he is afraid that it is only hundreds of zhang high, and the radius is even more thousand.

On the top of the big hole, there are countless sharp stalagmites standing upside down, and the tips of the stalagmites emit a terrifying cold light.

"Brother, this is where our Leng Clan's Ice Flame Cold Spring is located, you can just do it, I'll go first." The fat man's voice came suddenly.

Ling Feng looked back, after the fat man said this, he couldn't wait to withdraw quickly, and before he could say anything, the fat man's figure was already gone.

But at this moment, suddenly another gust of wind blew, but this gust of wind made Ling Feng shiver, this gang custom was really weird, it gave people the feeling that it was cold and hot, without thinking too much, he hurriedly blessed himself with a soul power protective shield to resist this strange wind.

At this time, Ling Feng understood why the fat man couldn't wait to leave as soon as he arrived here, it turned out that this was really not a place for people to stay.

With a wry smile, he came to a bare rock dozens of feet high, and below this rock, a bubbling cold spring was gushing out of its rock crevices.

This trickling cold spring, when it gushed out, there was also a kind of jumping white light point in it, it was expected to be the ice flame that the fat man said, Ling Feng leaned out his spiritual sense and wanted to sense this ice flame, but his spiritual sense had just touched the surface of this ice flame, and suddenly he almost devoured this spiritual sense, which made him startled, and quickly took the spiritual sense back.

However, although the power of this ice flame startled him, there was a look of surprise on his face, the higher the melting degree of the ice flame, the more beneficial it was for him to refine the Horcrux.

After figuring out the characteristics of this ice flame, Zhan Zai's spiritual sense looked around, and after finding that there was nothing unusual in this place, Ling Feng's face showed a look of satisfaction.

As soon as he touched the space hand, he took out dozens of high-grade magic crystals, and spent a stick of incense time to arrange these magic crystals according to a simple protective formation, and then injected a soul power into the magic crystal in the middle, only to hear a 'hum', a light mask the size of two zhang shrouded Ling Feng, and then with the disappearance of the light of this light cage, Ling Feng seemed to have disappeared into this place out of thin air.

With this formation guarding with both concealed exercises and defensive functions, even if someone with bad intentions comes, he won't be able to find himself for a while, and even if he does, this formation can resist for a while, enough for him to react.

Subsequently, Ling Feng arranged two more touching prohibitions at the entrance to the cave, with the prohibition of his current cultivation, unless the person who came was a master of the peak level of the Soul Heaven, it was absolutely impossible to find out, and even if he was a Soul Heaven master, if he was not very careful, it was very likely to touch the prohibition.

Although it is very likely that doing these auspicious things is superfluous, and there is no one nearby at all, it is better to be careful than to make a mistake, after all, what you are going to do next must not be discovered by others.

Entering the concealed formation, Ling Feng flipped over and took out a crystal clear jade bottle, the cork was opened, and a clear fragrance suddenly rushed to his face, and there were some crystal jade powder inside.

On the surface, these powders had no aura except for the fragrance they exuded, and there seemed to be nothing special about them, but Ling Feng's face showed a precious and important expression.

Divine jade powder!

This is still from Elder Mei Jian, and it is said that this powder not only has the miraculous effect of healing wounds and diseases, but also can be used to refine Horcruxes and raise their levels.

Although there is only a one or two percent chance of success in raising the level of the Horcrux, even this effect has really reached the level of rebellion, I really don't know how Elder Mei Jian got this kind of treasure.

I couldn't figure it out, Ling Feng didn't think about it anymore, and then he flipped his hand again, and with a dazzling flash, a pair of son-mother swords appeared in front of him, this was a ground-level horcrux that could make everyone crazy about it.

However, looking at this Horcrux, Ling Feng didn't have any feelings, but looked at the Divine Jade Powder in his hand, and his heart became inexplicably nervous, no wonder, there were four Ground-level Horcruxes on him, even if the melting failed, there was still a chance to refine again, but the Divine Jade Powder was only used for the second time.

If the two fusion Horcruxes are successful, then next, it is necessary to use the earth-level Horcruxes to do it, and there can be no tricks to refine and purify the Horcruxes to improve the level of the Horcruxes.

Looking at the jade bottle lying in the palm of his hand and the Horcrux on the ground, Ling Feng didn't dare to start, it was no wonder that a failure, but it was a ground-level Horcrux reimbursement and the amount of a decaying Divine Jade Powder, both of these things were distressing to think about.

After a long time, he took a deep breath, and finally picked up one of the souls as if he had made a great determination, held it in the palm of his hand, closed his eyes, and without distractions, he mobilized the soul power in his body and stretched towards the cold water in the rock.

The little bit of white light in the cold water, under the manipulation of Ling Feng's soul power, slowly separated from the cold water and condensed together, from thin to thick, until this point of light condensed to the size of a palm, the speed of the white spot condensation gradually slowed down, and a white flame also began to tremble slightly.

Seeing this white flame, Ling Feng breathed a sigh of relief, and as soon as his mind moved, the pair of swords on the ground escaped into the ice flame, as soon as the Horcrux and the ice flame came into contact, the two sides immediately "fought", the ice flame and the Horcrux trembled, and a dense "crackling" cracking sound sounded sound.

As time passed, the steady stream of ice flames finally engulfed the Horcruxes, and the crackling sound gradually subsided, but Ling Feng knew that it was still very early to refine the Horcruxes at this time, and at the very least, it was necessary to use more violent ice flames, so that it would last for four or five days, so that it would be possible to completely melt the ground-level Horcruxes so that they could be fused with other Horcruxes.

Thinking of this, the ice flames under Ling Feng's control became more and more dazzling, even reaching the point of being the size of a fan, enveloping the entire Zimu Sword in it.

In this way, after five or six days, until the Zimu Sword had completely melted into a mass of liquid, Ling Feng summoned the Heavenly Sword in his body and threw it in.

With the entry of the Heavenly Sword, the demand for Ice Flame was obviously higher, so from a distance, Ice Flame had become a huge fireball, and Ling Feng was becoming more and more difficult to control.

After another two days like this, maybe there was a reason for the Ice Flame to increase, Wu Hook actually turned into a liquid in only two and a half days, at this time Ling Feng knew that the time to fuse the Horcrux had come, so although it was already very difficult to control the Ice Flame, now was not the time to be sloppy, and he was more and more concerned about the Ice Flame under control.

When he felt that the time was ripe, he was about to put the Divine Jade Powder into it, but at this moment, a muffled popping sound came from the Ice Flame, although the sound was not loud, but it made Ling Feng's heart sink, and his face suddenly became ugly.
